3DTiles 1.1 support for las/laz point clouds

Hi,

I’ve noticed that when tiling an las/laz it tiles it to 3DTiles 1.0 but a .ply is tiled to 3DTiles 1.1. I was wondering if there’s a reason why las/laz aren’t being tiled to 1.1 or if this is on your road map to change for the future?

I’ve asked our tilers team, but my guess is that the ply tiler was written some time after 3DTiles 1.1 was formalized, and the las tiler was written before.

I’ve also asked them if there are plans to update.

Is this causing issues in your workflow, or potentially will change it if/when the update comes?

Hi Fordi thanks for your answer, would be great to hear if there are any updates from the tilers team.

I’m fine using 1.0 so no current issues, but just wondering what reasons there would be to use 1.1?

3DTiles 1.1 is uses glTF content types instead of the 1.0 data types, making it more industry standard and more performant, since there’s no translation step to get its information into the rendering pipeline.

Thanks Fordi,

Another quick question, is there any documentation for using a PLY as a point cloud? I’ve tried tiling some simple ply files and they are failing in the tiling pipeline.

Did the tiling team confirm if there were plans to updated the las tiling to 3DTiles 1.1?
